Filed: 2000-04-20
Granted: 2002-01-10
Abstract: FIELD: mining industry; applicable in sloping of high benches in opencast mining of kimberlite deposits. SUBSTANCE: method includes drilling of holes of contourside row to height of at least one working subbench at a distance of at least 14 hole diameters from design contour, then drilling of contour row holes in plane of formed high bench through its entire height, and the second row holes in each working subbench. Holes are charged with explosives and blasted, and broken rocks are withdrawn. First, loaded with charges and blasted are holes of contourside row, then the second row holes of upper working subbench, contour holes and the second row holes in each underlying working subbench. In this case, contour row holes are charged in lower part for height of underlying working subbench with charge density of 1-2 kg per meter run, and in upper part, they are charged with circular gap between charges and charge density of 4-8 kg per meter run. Broken rocks are withdrawn, first, from upper working subbench, then from contour zone and, at last from each underlying working subbench. EFFECT: increased stability of high benches due to reduced formation of fractures in rock mass behind contour and formation relatively smooth surface of bench slope. 3 dwg

Abstract: FIELD: oil extractive industry. 
     SUBSTANCE: method includes drilling of force and product wells, pumping of displacing liquid into force well and extraction of bed product through product well. During drilling process upper portion of clays is opened, which are subject to swelling and crumbling. After that drilled portion of well is reinforced by lowering operational column. Then drilling is continued with a chisel of lesser size and fully productive bed is opened by drilling solution at balance and or depression to retain collecting properties of bed. During drilling below lowered operational column gas armored cable testing is performed. On basis of results of testing and of slurry analysis decision is taken about necessity of stopping the drilling or further deepening. If productive bed is rentable, it is extracted by open pit-face with backfilling with coarse-grained sand. After full extraction of bed and performing isolation operations in bed, according to analogical plan the rest of lower beds is opened and extracted by drilling in series. If walls of productive beds are prone to crumbling, they are covered by profiled cover or tail piece made of easily drilled material.
